Abstract

A method for determining processed image data about a surround field of a vehicle includes a step of combining a map information item with a position and an orientation of the vehicle and with an image of the surround field acquired by a surround-field monitoring device of the vehicle, in order to obtain a position-specific image of the surround field. In addition, the method includes a step of processing the position-specific image so as to include at least one symbol that is assigned to a classified object in the position-specific image, in order to determine the processed image data.

Claims

1. A method for determining processed image data of a surround field of a vehicle, comprising:

combining a map information item with a position of the vehicle, an orientation of the vehicle, and an image of the surround field acquired by a surround-field monitoring device of the vehicle, in order to obtain a position-specific image of the surround field; and

processing the position-specific image so as to include at least one symbol which is assigned to a classified object in the position-specific image, in order to determine the processed image data.

2. The method as recited in claim 1, further comprising:

adapting at least one of an orientation and scaling of the symbol to the classified object in the processed image data.

3. The method as recited in claim 1, wherein in the processing step, the position-specific image is processed so as to include a portrayal of distance, wherein the portrayal is formed in order to represent in the processed image data at least one of (i) a distance between a classified object and the vehicle and (ii) distance lines in an open space navigable for the vehicle.

4. The method as recited in claim 1, wherein in the processing step, the position-specific image is processed based on at least one of an anticipated path of motion of the vehicle and a detected trajectory of the classified object.

5. The method as recited in claim 1, wherein in the processing step, an object relevant to a current driving task of the vehicle is determined and highlighted in the processed image data, and wherein a degree of the highlighting is a function of a distance of the relevant object to the vehicle.

6. The method as recited in claim 1, wherein:

the map information item includes information about a parking space, the map information item being combined in the combining step with the position and the orientation of the vehicle; and

in the processing step, the position-specific image is processed so as to include a symbol associated with the parking space.

7. The method as recited in claim 6, wherein:

the map information item is received by at least one service remote from the vehicle;

the map information item includes information about a fee to be paid for the vehicle; and

data are transmitted to the service remote from the vehicle, in order to pay the fee.

8. The method as recited in claim 6, wherein in the processing step, the position-specific image is supplemented with a digital map from the map information item.

9. An information system for determining processed image data about a surround field of a vehicle, comprising:

a device for combining a map information item with a position of the vehicle, an orientation of the vehicle, and an image of the surround field acquired by a surround-field monitoring device of the vehicle, in order to obtain a position-specific image of the surround field; and

a device for processing the position-specific image so as to include at least one symbol which is assigned to a classified object in the position-specific image, in order to determine the processed image data.

10. A non-transitory computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, perform a method for determining processed image data of a surround field of a vehicle, the method comprising:

combining a map information item with a position of the vehicle, an orientation of the vehicle, and an image of the surround field acquired by a surround-field monitoring device of the vehicle, in order to obtain a position-specific image of the surround field; and

processing the position-specific image so as to include at least one symbol which is assigned to a classified object in the position-specific image, in order to determine the processed image data.
